Title: Process for the manufacture of new reaction products of fatty acids
IPC: C11C3/08
Filed: 1933-03-02
Abstract: Materials useful as auxiliary agents in the textile and other industries are prepared by reacting glycide with free fatty acids containing at least eight carbon atoms, at least two molecular proportions of glycide being present for each molecular proportion of the fatty acid.  The products may subsequently be etherified or esterified, e.g. with inorganic or organic acids or their acid chlorides and anhydrides, chlorethane sulphonic acid, benzyl chloride sulphonic acid, ethylene sulphonic acid, alkylene oxides and epichlorhydrin.  The products are useful as emulsifying, cleansing, wetting, dispersing, impregnating and softening agents in the textile, leather, caoutchouc, lacquer and paper industries, as protective colloids in the dye industry, and in the cosmetic and pharmaceutical industries for preparing creams and salves.  An example is given of the treatment of linseed oil fatty acid with glycide to give an emulsifying agent; lauric, palmitic, oleic, linoleic and ricinoleic acids, as well as coconut oil fatty acids, may be similarly treated.  The samples are prepared by heating the reaction product of lauric acid and glycide with concentrated sulphuric acid at 30--35 DEG  C., phthalic anhydride at 110 DEG  C., or ethylene oxide at 180 DEG  C.  Specification 364,107 is referred to.ALSO:Materials prepared by reacting glycide with free fatty acids containing at least eight carbon atoms, at least two molecular proportions of glycide being present for each molecular proportion of the fatty acid, are stated to be useful as emulsifying and dispersing agents in the textile, leather, caoutchouc, lacquer and paper industries, and as protective colloids in the dye industry.
